What does a fixed transportation policy provide coverage for?

A fixed transportation policy is designed to provide coverage specifically for structures and infrastructure associated with transportation, such as bridges, tunnels, and communication instrumentalities. This type of policy is crucial for protecting these vital assets against various risks, including damage due to accidents or natural disasters.

The focus on bridges and tunnels highlights the need for coverage for fixed locations that facilitate transportation. These structures play a critical role in the movement of goods and people, and having insurance ensures that any damages or liabilities incurred can be addressed without excessive financial burden.

The other options tend to focus on movable or temporary assets rather than the fixed installations themselves, which is why they do not align with the purpose of a fixed transportation policy.
